The room we were staying is perfect for 3 or 4 pax. I was sleeping in the bunk bed, and it's the best bunk bed I've ever slept in. Bunk bed in places are often quite narrow and you might accidently knock on the roof or the base of the other bed on top, this one here is comfortably the tallest and widest bunk bed I've seen.
And like most air-conditioned places in BKK, this place is filled with this particular aroma, that kinda makes us feels like "home" even just for a few days stay. Best of all, there are 2 bathrooms in each floor, so it's super convinient!
Host is a very nice person, able to speak in Chinese, English, and Thai of course (maybe more I don't know haha), gave us some useful tips when we are in doubt (in food or massage place), and loves to make tea. The place is around 10 mins walk to Sam Yan Station? I didn't time, but I do recommend to take metered cab if you're travelling in 3 or more pax in BKK, it's probably the best and cheapest transportation (again if you're travelling in 3 or more pax) around the city.
I rarely give an all "5 stars" in airbnb, this one is really one of the best!
